SHUTTLE FOR Looms.

SPECIFICATION forming part of Letters Patent No. 378.895, dated Marche,188s,

` Application tiled September 26, 1887. Serial No. 250,717. (No model.)

.To all whom it may concern: y

Be it known that I, GUY C. MILLS, of Nashua, county of Hillsborough, andState of New Hampshire, have invented an Improvementin Shuttles forLooms, of which the following description, in connection with theaccompanying drawings, is a specification, like letters on the drawingsrepresenting like parts.

This invention has for its object to improve and simplify theconstruction of that class of shuttles wherein the bobbin is held uponthe spindle by an inside catch.

In this invention the groove within the bobbin is engaged by aprojection from one side ofthe spindle, and also by a lip of aspringcatch located at the opposite side of the spindle, as will bedescribed.

My invention consists, essentially, in the combination, with aspindle-body and bobbin having an internal groove, of a spindle havingat one side a bobbin-engaging projection, and with a locking springhaving alip to enterthe groove at the inner side of the bobbin, but atthe opposite side of the spindle.

Figure l shows in longitudinal section a part ot' a loom-shuttleembodying my invention, and Fig. 2 is a modification to be described.

The shuttle-body A has pivoted to it at a a spindle, cf, having at oneside a projection, as a3, to enter the inside groove, b, in the bobbinb, (shownv by dotted lines,) the projection acting to retain the bobbinon the spindle, all as usual. The spindle is acted upon byaspringpressed pin, c, which lnormally keeps the spindle down in theshuttle-body. The heel of the spindle has riveted to it aspringcatch, d,having a lip, d2, which enters the chambered base of the bobbin, andengages the inside groove therein at that side of the spindle oppositethe projection a3.

The shuttlebody has a pin, e, so located as to be struck by the springwhen the spindle is turned out of the shuttle-body, as in dotted lines,Fig. l, the pressure of the spring against the said pin pushing the lipof the springcatch back out of the inside groove iu the bobbin.

As described, it will be seen that the bobbin is held positively atitsinterior at two points and at opposite sides of the spindle, thusholding the bobbin very securely.

In the modification shown in Fig. 2 the inside catch, d, having the lipd2, is attached to a shank, h, extended through a hole in the head ofthe spindle, the shank being surrounded by a spring, as h, the lower endof the shank being sufciently upset or enlarged, so as to limit theoutward movement of the lip.

In practice, when the spindle is turned ont from the shuttle, the headof the stud will hit against a shoulder, as 7a3, in the wood of theshuttle-bobbin. (See Fig. l.)

I claim- The shuttle-body, the spindle provided with the projection asat one side, to engage au inside groove in the bobbin,and an independentspring-catch, d, located at the opposite side and attached to the heelof the spindle, the said springcatch having at its free end a lip, toalso enter and engage an inside groove in the base of the bobbin,combined with means to operate the said spring-catch to relieve thebobbin when the spindle is turned out of the shuttle-body, substantiallyas described.

In testimony whereof I have signed my name to this specification in theprescnce of two subscribing witnesses.

GUY C. MILLS.
